FIREPROOF PARTITION.

SPECIFICATION forming part of Letters Patent N o. 7 21 ,962, dated March3, 1 903.

Application filed October 27, 1902. Serial No. 128,986. (No model.)

To all whom it may concern:

Be it known that LHERMANN MARINe-acitizen of the Empire of Germany,residing in Darien, in the county of Fail-field and State ofConnecticut, have invented certain new and useful Improvements inFireproof Partitions, of which the followingis a specification.

This invention has reference to an improved fireproof partition which isbuilt up of individual blocks that are connected with each other in sucha manner that a comparatively light yet strong partition-Wall is formed;and the invention consists of a fireproof partition made ofpartition-blocks formed of cement with longitudinal openings of largeand small diameters, anchor devices for connecting said blocks, means insaid small openings attached to said anchor devices,reinforcing-framesembedded in the side portions of said blocks, andcorner-pins connecting said reinforcingframes, as will be more fullydescribed hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a top View of a moldfor making my in] proved blocks for fireproof partitions. Figs. 2 and 3are side elevations of two different forms of block. Figs. 4 and 5 areportions of partition-walls built up from blocks shown in Figs. 2 and 3.Figs. 6, 7, and 8 are horizontal sections of partition-blocks providedwith openings of different cross-sections. Figs. 9 and 10 are horizontalsections showing the anchor connections between blocks and partitions,and Figs. 11, 12, and 13 are detail views of the different anchorconnections employed. 7

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents my improved block for fireproofpartitions, which block may be made in shape shown in Figs.

2 and 4, in which the blocks are alternatelyprovided with grooves andprojections in their horizontal sides, so as to form a connection in thenature of a groove and tongue, or the blocks may have rectangular faces,as shown in Figs. 3 and 5, in which case the blocks are superposed oneabove the other and connected by suitable mortar joints. Each individualblock is preferably made of cement or other plastic material which setsafter being molded into shape and provided with verticalopencross-section, as shown in Figs. 6 to 10.

ings a of polygonal, round, elliptical, or other Intermediately betweenthe larger vertical openings a are formed smaller openings a of round,rectangular, or other cross-section, while the separating portionsbetween the larger openings are provided with openings a extendinglongitudinally of the block, all of these openings being for the purposeof making the block as light as possible-and forming air-spaces in thesame. To impart the required degree of strength to the partitionblocksand protecting the same, so as to enable them to carry the pressure ofthe load which may be placed upon them, and for permitting the shippingand handling of the same without injury, the blocks are reinforced bymeans ofskeleton frames'B'adjacent the side walls, that are formed ofnarrow metallic straps crossing each other and which are placed aroundthe transverse metallic pins B inserted into the corners of the blocks,as shown-in Figs. 2 and 3. The skeleton frames, as shown in Figs. 6 to10 by dotted lines, are embedded in the cement of the body of the blockby being placed in position in the mold, the tubes 0 c for forming thelarger and smaller openings being also placed in position and supportedby an oblong frame F, in which the cement is rammed into the spacesbetween the tubes within the spaces inclosed by the inner faces of theframe F. The frame F, with the molds, is supported on the bedplate f,and'when the cement is fully rammed around the tubes and skeleton framesthe top is made level with the top ofthe frame F by means of a scraper,so as to produce thereby blocks of uniform size. After the material hasset the tubes are withdrawn from the same, the blocks being then removedfrom the mold by opening the supporting-frame. In this manner fireproofblocks for partitions are obtained which are of great lightness and yetreinforced in their side portions, so that the blocks are capable ofbeing shipped from the factory to the place of use and of being handledto be put up without injury. The metallic skeleton frames also increasethe strength of resistance of the block against the pressure of the loadon the same. By the construction of the block the individual portions ofthe same at both sides of the openings form individual pillar portions,as indicated in the middle block shown in Figs. 6 and 7 by thecross-hatched portions, which individual pillar portions, however, areconnected firmly together by the vertical reinforcing-frames in the sideportions of the blocks, which are tied around the transverse collar-pinsB. WVhen a thicker and stronger partition-wall is to be formed, twoparallel partition-walls have to be connected together, in which casethe walls are anchored by connecting-pieces E, secured by rods e,dropped into the small openings of the blocks, as shown in Fig. 9, orS-shaped anchoring-straps may be used, as shown also in Fig. 9. Theadjacent ends of individual blocks may also be connected by means of ananchor or intersecting straps which are applied to rods dropped into thesmaller openings of the blocks, said anchor connecting the parallel aswell as the individual blocks of the same. The connections are employedwhen partition-walls at right angles are to be connected, as shown inFig. 10, the locking or anchoring straps E being either straight or ofdiagonally-intersecting S shape, as shown in Figs. 11, 12, and 13.

My improved fireproof partition blocks have the advantages that theycombine lightness with strength, can be made ready for use at thefactory and shipped to the place of use, can be quickly erected andconnected with each other by the anchoring connections described, andthat they impart to the cement body increased resistance to the pressureby means of the metallic skeleton frames embedded in the side walls ofthe blocks.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A block for fireproof partition-walls, consistingof a cement body provided with vertical channels of suitablecross-section and transverse openings in the connecting portions betweensaid vertical openings, metallic reinforcing skeleton frames in the sideportions of said blocks, and transverse cornerpins connecting saidframes, substantially as set forth.

2. A block for fireproof partition-walls, consisting of a cement body,provided with large openings and with small openings intermediate thesame and adjacent the sides of the block, the connecting portions of theblock between said large openings being provided with transverseopenings, reinforcing metallic skeleton frames, embedded in the sides ofsaid block, and pins connecting said frames at their corners,substantially as set forth.

3. The combination, with individual partition blocks provided withlarger vertical openings and intermediate smaller vertical openings, ofreinforcing metallic skeleton frames in the side walls of the blocks,and connections atthe abutting ends of the blocks, said connectionsbeing formed of straps applied to metallic rods placed in the smalleropenings of the blocks, substantially as set forth.

4:. The combination of adjacent partitionwalls formed of individualblocks provided with larger vertical and intermediate smaller openings,said blocks being reinforced by metallic skeleton frames embedded in theside portions, and anchoring connections extending from one to theadjacent wall, said connections being formed of straps applied to rodsplaced into the smaller openings at the adjacent ends of the blocks ofthe partitionwalls, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.

I-IERMANN MARING.
